Cat sneezing, watery eye, sleeping more: Is it an upper respiratory infection?
Hello. I would say you are exactly right, that Simba has an upper respiratory infection, essentially a cold. If he is eating & drinking fairly normally, then you probably do not need to rush him to the vet as colds often just need to run their course. As to why your female seems fine? Well, there is a good possibility she could start sneezing in the next week or so. Again, if the symptoms are mild, you may not need to do anything, but if either kitty quits eating or the ocular nasal discharge becomes thick or green, or you detect any problems breathing, then you will need to have them treated by your veterinarian. If your kitties have not had a full series of kitten vaccinations, which include the most commonly encountered upper respiratory infections a cat can contract, please make sure you complete the series as soon as everyone is feeling better. Thanks for using Petco Pet Education Center, formerly Petcoach.
